Pink Flowering Gum, Calypso Flowering Gum

The Story

Plant Bio

Corymbia ficifolia, native to a restricted coastal strip of Western Australia, is a small evergreen tree renowned for its dense canopy and spectacular summer flowering. The species thrives in well-drained, sandy soils and Mediterranean climates, producing large terminal clusters of bright blossoms followed by heavy, urn-shaped woody capsules.

'Calypso' is a compact, grafted cultivar selected for its reliable, dense, rounded habit and striking salmon-pink to deep pink flowers. Grafting onto hardy rootstocks like Corymbia gummifera or Corymbia intermedia allows this selection to tolerate a broader range of soil types and pathogens than seed-grown specimens.

Uses & Benefits:

Produces a dense, rounded canopy of dark olive-green foliage topped with large, showy clusters of salmon-pink flowers throughout summer, followed by decorative woody gumnuts.

Grafted rootstock provides high adaptability to diverse soil types and increased resistance to soil-borne pathogens compared to seed-grown species.

Provides a significant summer food source, attracting nectar-feeding native birds, native bees, and beneficial insects to the garden.

Planting

How to Grow

Select a planting site in full sun with excellent drainage, avoiding low-lying areas prone to waterlogging.
Dig a hole twice as wide as the root ball but to the same depth, ensuring the graft union remains well above the soil line.
Backfill with native soil, firm gently, and water thoroughly to settle the roots without adding fertiliser to the planting hole.
Apply a thick layer of coarse organic mulch around the base, keeping it clear of the trunk to prevent collar rot.

Pro Tip

Remove heavy clusters of developing gumnuts on young trees immediately after flowering to prevent the weight from snapping the branches before the structural wood matures.

Keep It Thriving

Care Guide

Do

Water regularly during the first summer to establish a deep root system.
Prune lightly after flowering to maintain a compact, balanced canopy.
Use a low-phosphorus native fertiliser sparingly in early spring.

Don't

Do not prune aggressively into old, leafless wood as it will not regenerate reliably.
Do not allow heavy clay soils to remain waterlogged around the root zone.
Do not apply standard high-phosphorus garden fertilisers.
